SPECIFICATION forming part of Letters Patent No. 378,12', dated February 2l, 1888.

Application filed February '7, 1S8I. Serial No. QQSJSG. (No model.)

To @ZZ 107mm t may concern.-

Be it known that I, J. BENNETT WALLACE, a citizen of the United States, residing in Ohicago, in the county of Cook and State'of Illinois, have invented a new and useful Improvement in Generating Vapor-Burners, of which the following is a specification.

This invention relates to the same class of hydrocarbon-vapor generating burners for gasolinestoves as that shown in patent to me of March 29,1885, Xo. S14-,404; andsome portions of the invention are designed to improve the construction particularly set forth and` claimed in said patent.

One object sought in the present invention is to lessen or obviate the disturbance caused by the slight explosions which are continually occurring in t-hat part of the burner where the vaporization takes place,and which are due to the sudden change of particles of gasoline orof foreign matters contained therein into vapor. These explosions, especially in those burners wherein a tube of small diameter is employed as the generating or vaporizing part of the apparatnaaiect the llaine,and cause a sputtering and unevenness thereof, which is objectionable and disagreeable as well. This evil I overcome by interposing between the generator and the burner a chamber,in which a body of vapor is always present, and in which body the disturbance caused by the explosions will be lost or cushioned, and thus i'ail to reach or affect the llame.

Another feature of the invention consists in conducting the freshly-formed vapor to the bottom of this chamber and drawing it away from the top thereof, so that the direct communication between the generator and burner, which would be apt to carry the disturbing effect of the explosions to the ilarne,is broken and opportunity is given the vapor to diii'use itself throughout the chamber instead of proceeding on :its way to the burner in an unbroken and continnonsly-moving current.

Other-features of the invention relate to the construction ot' the metal casting in which the gas-chamber and the various passages are formeda I also employ in my present invention an improved form oi' deflector, whereby the vapor may be deflected from the induction-tube of the burner to the under side of the base plate, in order that the latter and the generator, which is in metallic contact with the burner, may be kept heated when the stove is not in active use. Instead of slotting the in duction-tube of the burner and employing a delieetor which will move into said tube, and which when mot in use forms a part of the wall of the latter, as in my said Patent No. 814,404, I make the tube in two parts-an upper and a lower part-and attach thelatter to the deiieetor7 which is hinged to move in a similar manner to the detlector of the previous construction, so that when the deflector is moved into position for operation its lower end takes the position previously occupied by the movable portion of the induction-tube. I also form this movable portion of the induction-tube with a iiaring receivingemouth and a contracted deliverybpening, and separate it from the upper or immovable part of the tube, this latter being also provided with a Haring month. It results from this construction that more air is admitted to the burner with the vapor and more perfect combustion produced than with the previous construction and the velocity of the current increased after the well-known principle employed in injectors.

The movable portion of the induction-tube may be appropriately termed the mixingtube#7 and such term will be applied to it throughout the speciiication.

The generating or vaporizing tube, which is one of small diameter, I now locate above the plane of the base-plate of the burner, and at one side thereof, so that the flame from the burner will envelop it, and thus render it more effective. The vertical feed-pipe, or, as it is termed among the manu faeturers, the stand-pipe, I provide with a valve regulating the admission of the oil, and also at the lower extremity with a trap in which the sediment from the gasoline will collect and from which it may be removed by loosening a screwplug in the bottom of the trap.

In the accompanying drawings, which form a part of this speeitication, and in which similar letters of reference indicate like parts, Figure l is a front elevation of a burner embodying my present improvements. Fig. 2 isa plan with the base-plate partially broken away.

Fig. 3 is a side elelvationftwo ,of the valveoperating wheels shown in"Fig.'I beingV left off. Figs. 4. and 5 are sections of the defleetor, the mixing-tube, the inlet-tube of the burner, and the vapor-feed pipe and its valve, taken upon the line .fr a: of Fig. 8, the movable parts being shown in different positions in the. two gures. Fig. 6 is an enlarged vertical section of the lower part of the stand-pipe or feedtube. Figs. 7, 8, 9, and ld are sections upon the lines 7 7, S 8, 9 9, and 10 10, respectively, of Fig. 2. Figs. Il and. 12 show dierent ways in which the deiiector and mixing-tube may be hinged. Fig. 13 is an elevation of the generating and non-generating burners and their connections. l

In said drawings, A represents the baseplate, B the cap of the burner, and. C is the gasoline feed or stand pipe. The latter is inserted in the under side ofa casting, D, formed in one piece with base-plate A, or attached thereto, and opens into a passage, d, in said casting. From this passage a short pipe, e, extends to and connects with one end on the generating or vaporizing tube E, which, as shown, is sufficiently elevated above the baseplate and near the burner to insure its being enveloped or actively impinged upon by the ame from the latter.

From the other end of generatortube E depends a pipe, c', which extends to the bottom of the cushioning or venting chamber F, formed in said casting D. In this chamber the dis turbing effects of the slight explosions due to the vaporizing are dissipated and lost, the body of vapor in said chamber acting as a cushion in absorbing the impulses created by the eX- plosions. All the freshly-formed vapor is first conducted to this chamber, and is drawn from thence to the burner or burners used in the stove. The supply for the generator-burner"A t. e., the burner shown in the drawings-may be taken from the bottom of chamber F by the pipe G G', and this is the preferable way, because through this pipe the heavier vapors will more readily nd exit, and any unvaporized or impure portions of the gasoline will be thereby drawn away from the chamber; but the vapor to feed the non generating burner or burners V V is preferably drawn from the top of the chamber-as, for instance, v

through passage f f', formed in the casting D and connecting with conduit H, opening into pipe H', leading to one of the burners-or by the pipe t', connecting with pipe J, opening into pipe J', leading to the other of the burners. By thus drawing from the top of the chamber the vapor is compelled to rise through the chamber, and the continuity of the current from generator to burner is thus broken up to some extent. 'Ihe non-generating burners thus fed are less likely to be affected by the disturbances in the generator than the generatorburner itself, though I have found that the cushioning-chamber very eectually protects the latter.

Any construction of non-generating burner or burners may be em ioning-ehambei. Y

The casting D embodies passage d and chamber F when east, and the pipes G G and base-V plate may also be cast in one piece therewith. The passages ff are drilled after casting, as well as the pipes G G. The generator E and the pipes e e are secured to the casting by brazing or soldering the latter, while the pipes H, i, and .I are united by screw-joints.

In a lateral extension, g, of the pipe G is located the needle-valve b, controlling the generator-burner. Through this valve the vapor is jetted into the burner induction-tube, the lower portion of which is formed by the short tube K, having a flaring inlet and contracted delivery, and. which I call the mixingtube, and which registers with the upper portion, L, ofthe burner inductiontube, shown as passing through the base-plate A. Air is free to enter and mingle with the vapor, both above and below the mixing-tube K, there being an open space between the valvejet orifice and the mixing-tube, and also between the mixing.4 tube and the tube L. The mixingtube is east with and supported .from the hinged deliector M, and when the latter is to be used both are moved to the right, so that the mouth of the deflector registers with the jet-oriiiceand conducts the vapor to the under side of the baseplate A, where it serves to keep the parts sufficiently heated to enable the stove to be put into active use without delay at any time.

The defleetor may be hinged to the tube L,

this@ with ,my @ushas shown in the main figures at m, or the hinge may be located upon the farther side of the tube and mixing-tube, as in Fig. Il. or at top and bottom thereof, as in Fig. l2. The use of this defleetor is so fully set forth in my previous patent that I do not new give any eX- tended description thereof. The operating-y handle N, which is secured to the defleetor, bears with sufficient friction on the pipe G to hold the dedeetor and mixing-tube in either position.

O and o are the stems of the needle-valves used in connection with the non-generating burners, and an. represents the pan used to eontain the igniting-fiuid employed when the stove is started.

At the bottom of the stand-pipe is a valve, c,whereby the feed-supply of gasoline is regu lated, and below this valve is the chamber P, to which the fluid in the first instance is admitted. This chamber I tap at the bottom and fill the opening with a screw-plug, R, having a central passage, r, and lateral vent s, so that by turning down the plug a short distance the vent is exposed and. the contents of the chamber l? may be drawn on'. As whatever sediment contained in the gasoline is very apt to settle in said chamber P, the plug adords a convenient means for getting rid of the same, the chamber thus acting as a trap and assist ing in purifying the gasoline.

I am aware that a large generating-chamber has heretofore been employed in combination IIO with a comparatively small snperheating. chamber receiving the vvapor from the first chamber and discharging it to the burner. Such superheatingchamber was, however, in much closer proximity to the flame than the generator itself; but the explosions take place at the point of greatest heat, and hence are much more apt to occur at the superheatingchamber than at the generator' in this old construction, and such explosions, not finding vent at that chamber by reason of its contracted character, inipartimpulses to the current leading from it to the ilalne and cause the latter ,to sputter. In my invention I have no superheatin g-chamber, but snbj ect the fluid to the greatest heat at the generating-tube, in which there is no ventingnoom wherein the disturbances caused by the explosions may be dissipated, and I locate the ventingbhamber between the point of greatest heat and the burner. In my construction,also, all the explosions are taken care of instead of a portion only, as is the case With this old forni of stove.

I claim- 1. In a vapor-stove, a generatingburner consisting of a burner proper, a generator, a cnshioningchamber independent of the gen erator, a conduit extending from the generator to the cushioning-chamber, and a feed-conduit from said cushioning-chamber to the burner proper, in combination With a non-generating burner and a feed-conduit connecting such non-generating burner With the cushioningchamber of the generating-burner, substantially as set forth.

2. In a vapor-stove, a generating-burner consisting of a burner proper, a generator, a cushioning-chamber separate from the generator, a conduit extending from said generator to the bottom of said cushioning-chamber, and a feed-conduit from said chamber to the burner proper, in combination with a nongenerating burner and a feed-conduit from the top of said chamber to said last-named burner, substa-ntiall y as set forth. a

3. The combination, in a generating vaporburner, of the burner-cap B, the plate A under said burner-cap, a casting, D, located at the side or" said plate, and the generating-tube E, located above the plane of the plate A and in proximity to the burner B and connected t0 said casting by feed and discharge pipes e e', substantially as specified.

4. In a vapor-burner, the casting D, in one piece with base-plate A and having,` chamber F and passage (Z formed therein, in combination with burner B, plate A, and the generar tor-tube connecting said chamber and passage, substantially as set forth.

5. In a generating vapor-burner, the com bination,\vith the induction-tube and needlevalve, of the movable mixing-tube K, located between the valve and theinductiontube and at a remove from the latter, so that the air will be admitted to the vapor at the mouth of both tubes when both are in use simultaneously, substantially as specified. v
